Photosynthesis and Respiration: a Comparative View

Photosynthesis and Respiration: a Comparative View

Difference between Photosynthesis and Respiration


  • Photosynthesis occurs in chlorophyllous tissues
  • Photosynthesis goes on only in presence of sun light
  • Water and carbon-dioxide are the raw materials
  • Photosynthesis absorbs carbon-dioxide and gives out oxygen
  • It is an anabolic process
  • In this method planers gain waight
  • Photosynthesis produces glucose and oxygen.



  • Respiration occurs in all living cells
  • Respiration goes on day and night
  • Glucose and oxygen are the raw materials
  • Respiration absorbs oxygen and gives out Carbon-dioxide
  • It is a catabolic process
  • In this process plants lose weight.
  • Respiration produces carbon-dioxide, water and energy.
